We've been selling the JR GSR for the last 10 years, importing them through Horizon. Then about 1 1/2 years ago JR released the GSR260Z, an upgrade to the GSR260 which we had been selling for years. (We put one in service in the AP world for R&D).
The heli is nice but the landing gear along with basic cost hurt sales on the heli dramatically. Do to this JR released the GSR260 Sport to try to reduce the cost. We had a GSR260 Sport sent to us about a year ago to test in our market. JR has all 3 heli's on the market now which Horizon is the Distributor for in the USA.
If you call Horizon about any of these heli's you will be sent to us. We've stocked all the parts and kits for the GSR for over 9 years. We also stocked the GSR260Z Sports until about 6 months ago.

Our market isn't sport flying it's industrial in the Aerial world. After DJI releasing auto pilots for the serious business person we sat down evaluating the real world market if you want an electric system. (Quad/T-Copter or Tri just makes more sense)

We sat down at this point and decided to move forward on a heli that could be designed around the GSR heli we have sold and been flying for a decade in real world conditions.(a 4 stroke we have been working on for over 4 years off and on) Eliminating the 2 stroke motor moving into the world of the new anti vibration 4 stoke engines was the heart of the design. Something that we could use the torque and not HP. Get rid of the carb tuning, dialing in the curves all the problems the 2 stroke engine causes including the sound. We wanted the simplicity of the electric heli with the flight time and sound never seen before in a gas heli.

This is where the AF-GSR-4 came from. 2 models are being released the end of this month (35cc and 40cc units) These are GSR rotor heads and tail units with the rest of the heli a completely new concept manufactured by AirFoil. This heli fly's incredibly smooth do to the gyroscopic effects of running a larger flywheel. The sound is like a full scale R22 just very quiet. Smooth, quiet, with flight times never heard of before of 1 hour stock with the ability to fly in excess of 5 hours.

Picture of the new AF-GSR-4. (More to come soon)

We think the future of Gassers. Designed for the AP world but a heli that brings fun back into the R/C world of gas heli's with the sound that you are flying a full size helicopter.

how much is the package? who makes the engine? and what kinda reliablility does the engine offer? Flight times of 1 hr sounds good to me!

if im not blade bogging youll find me pack puffing

Setup is everything, All my heli's can fly far better than I can pilot them

The AF-GSR-4 Heli sounds like a Heli I would love to own... any Vidoes ?

Does it use a Honda motor?

Is the motor somehow mounted with rubber isolation mounts (like they do on a car)?

With that Honda 4-stroke engine, you could get perhaps thousands of hours of run time.

If you think that sounds great wait a couple of days and I will have them post onboard video from the new system. The one in the video is the Honda GX35. We no longer use that motor. That motor was R&D a few years ago.
We have a 35cc,40cc and 45cc for heavier payloads. These motors are new evolution 4 cycle engines with built in anti vibration technology. You can hold one of these motors in your hand while running , throttle up, and be amazed how smooth the engine is.

Shindaiwa, Echo, Stihl are just some of the national brands using the motor technology. All of the motors use no tune carbs with stock fans and exhaust. To make sure the motors are Ice cool in 100 degree weather, as quiet as possible with no hassles. The motors are all rated at 2500 hours time life before rebuild. To give you an idea how that compares to engines used now?

The Zenoah RC engine Vario and other R/C cars use has a 10 hour (TBO) Time before overhaul. The 26 and 231 Heli engine Zenoah offers have a TBO of 250 hours before you should replace the cylinder,rings and piston. The heli is not designed for 3D or huge HP. (no way to compare it to a Hanson) The engines work in a completely different way. The design is for payload, durability, simplicity, torque with low vibration along with huge flight times.

More to come the end of the month.

Thanks
John

doesn't apply for helicopter usage. myself and many others have run them for hours and hours with no issue. They are barely broken in at 10 hours of running

RC cars would be a very dirty environment and different

hopefully it is smooth though, the 36cc 4 stroke motor in my Stihl equipment is far from smooth at usable RPMs

If you're not flying a gasoline helicopter
You're paying 10 times too much for fuel!!

Low vibration would be good, but I've heard that one before. I will believe it when I see it. I trust a Honda engine, but that's about it.

More smoke blowing up our butt from John O just like always. 10 hours before overhaul ha ha I have hundreds of hours on mine.

Posting like a 3rd grader does[I] no one any good.[/I

Yep I have years on a 231 that is still perfect after 1000's of hours on the unit. These motors are great always have been. Those are Zenoah’s #'s, have been for years. If you love your motor I'm happy for you. Every vendor isn't going to 4 stroke technology because it costs less. It's because of durability, ease of use, simplicity. (The market demands it)

Almost every company now produces a new evolution 4 stroke motor. You are looking at the future like it or not. Once you fly one you will understand why they are. We're just bringing the future of all the other markets into the R/C world.

I quit flying 2 stokes a year ago once we had the design nailed. This isn't a sales pitch you can't even order one till next year. One company purchase every unit we could produce in Dec.

It’s like electric heli’s and Quads. The future is here. We’re just not staying in the past. It’s basic R&D for us moving forward.

Like I said more smoke blowing up our Waukazoo.
I've got nothing wrong with the future, but to tell somebody, only 10 hours and then they have to rebuild there engine is a flat-out lie!
I'm sure the four stroke engine will have its place in Market,
I'm sure it's smooth and quiet which would be nice!
good luck John Hope you do well. XGM/VGM

Will you have any demo engines at the Orlando blowout ?

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

yeah right, "anti vibration technology", and on a 4 stroke single piston...sure. let me guess, big heavy fan/flywheel with an integrated harmonic balancer, heavy this mounted on rubber that...same old overblown story, new wording...
The heli is not designed for 3D or huge HP.
= boring
The engines work in a completely different way
oh realy? as compared to what? The space shuttle maybe?
The Zenoah RC engine Vario and other R/C cars use has a 10 hour (TBO) Time before overhaul
What a load of BS...
To make sure the motors are Ice cool in 100 degree weather
So your engine maintains 32 degree head temp?

typical salesman...

showing a preference will only get you into trouble, 90% of everything is crap...

Let me guess you’re in college? Wonder why cars aren't all 2 stroke? Why dirt bikes are changing to 4 stroke and are smoother? tons of torque? 4 wheelers and so on. Basically any gas powered hand tool has a 4 stroke upgrade to improve performance.

The design isn't for 3D. Actually the 36cc is 1 lb. heavier then the G26 with less HP but more torque. The engines came out 10 months ago.

Kind of hard to be old news when your only 10 months old.

You make us entrepreneurs that have been in businesses 10-15 years is this industry seeing all the changes in the last 25 years as we have been flying since then wonder what the future really holds.

You show you served this country? Our systems are used by the DOD and now by NASA for the Mars Rover Project. We're not just selling product sitting still.

Actually I'm the owner (not salesman) that started in a garage 17 years ago launching a company 15 years ago and now I'm sending a product we designed to another planet. Kinda cool if you keep an open mind and leave the prick side behind. Anything is possible.

Yeah this does sound cool-I switched to gas because I just want to go to the field with a tank of gas, helicopter and transmitter and just do some sport flying. I do not have much time to fly so just going out Sunday's is something I look forward to. I also made sure to get Jewels for my Radicals-which I think are great helicopters-for me at least. This sounds interesting-keep us posted-what price range will the helicopters be around?

I look forward to the day I will be able to fly with a 4 cycle engine. The sooner the better. I don't, cann't, and have no plans to fly 3D. I am old and slow and like to fly low and slow. Bring them engines on, I want one for my Radical.

Jimmy, If it looks like a heli I like it.
